The road to complete arterial grafting for coronary artery disease.
In 1984, our department moved to the use of single, and subsequently, bilateral internal thoracic artery grafting which, when reviewed after 12 years, suggest the addition of a second internal thoracic artery is beneficial. The 10-year survival using all-cause mortality was 86.9% for bilateral internal thoracic artery grafting compared with 74.2% for the use of a single internal thoracic artery graft. The mortality rate ratio for single versus bilateral internal thoracic artery grafts was 1.4 (P=0.009). In 1995, we entered an era of total arterial grafting using combinations of radial and internal thoracic arteries. There have been no additional early complications in the first 2 years, furthermore the early results show that the postoperative creatinine kinase MB isoenzyme and the myocardial infarction rates were lower in patients receiving at least one radial artery graft compared with those not receiving a radial artery graft. Continued use of internal thoracic and radial arteries to achieve complete arterial revascularisation for patients with coronary artery disease appears justified.
